The film shows how the environment around a black hole changes as its gravity stirs the surrounding matter into a constant vortex. The image shows an unbalanced mass of light swirling around the supermassive black hole at the center of M87. < / P > < p > to make this film, the horizon telescope (EHT) collaboration mined old data about black holes and then combined them with mathematical models based on images released in April 2019 to show how the environment around black holes has changed over the past eight years. Although this depends in part on speculation, the results give astronomers a rich understanding of the behavior of black holes. Maciek wielgus, a radio astronomer at Harvard University in Cambridge, Massachusetts, and lead author of the study, said: “because the flow of material falling on a black hole is turbulent, we can see that the rings oscillate over time.” This achievement was published in the Astrophysical Journal on September 23, local time. “In a few years, it may really start to look like a film,” wielgus said After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
